LabVIEW调用MATLAB语言开发的算法的一些论文参考资料(LabVIEW calls the algorithm developed MATLAB language reference number of papers)

说明：  带通滤波。该程序用matlab实现梯形窗的带通滤波，可以直接调用(Band-pass filter. Trapezoidal matlab implementation of the program window with a band-pass filter, can be called directly)

对于周期图的功率谱估计,当数据长度N太大时,谱曲线起伏加剧, 若N太小,谱的分辨率又不好,因此需要改进。两种改进的估计法是 平均周期图法和平滑平均周期图法。Bartlett法:Bartlett平均周期图 的方法是将N点的有限长序列x(n)分段求周期图再平均。(For the power spectrum estimation of the periodogram, when the data length N is too large, the spectral curve fluctuation intensifies,   If N is too small, the spectral resolution is not good, so need to be improved. The two improved estimates are   Average Period Graph and Smooth Mean Period Graph. Bartlett method: Bartlett average cycle chart   Is to re-average the finite-length sequence x (n) of N points by periodogram.)

自适应滤波的课件，有需要的可以下载下来参考学习(Adaptive filtering courseware, there is a need to learn can be downloaded for reference)

设计一个切比雪夫滤波器，要求通带截止频率 ，通带最大衰减 ，阻带截止频率 ，阻带最小衰减 。要求绘出滤波器的幅频特性曲线。(Design a Chebyshev filter, the passband cutoff frequency required, the maximum passband attenuation, stopband cutoff frequency, stopband minimum attenuation. Requirements of the filter amplitude-frequency characteristic plotted curve.)
